Abstract

La invención se refiere a la cabeza de un proyector aéreo mejorado que reduce la vibración que se puede producir en la cabeza de un proyector aéreo y que se emplea para proyectar imágenes desde un panel LCD colocado en el escenario del proyector. Las mejoras incluyen añadir una placa de montaje entre el brazo soporte y la abrazadera de la cabeza. La placa de montaje está en voladizo desde el brazo soporte, y la abrazadera de la cabeza está sujeta mediante espaciadores colocados cerca del extremo de la placa de montaje que está lejos del brazo soporte. En realizaciones alternativas, la abrazadera de la cabeza se puede dividir en dos piezas separadas mediante espuma u otro material amortiguador de vibraciones, o un contrapeso que se puede añadir al conjunto de la cabeza por detrás del brazo soporte.
